Probability of minor piece pawnless ending

Dear Chess lovers,

 I am just wondering have you ever faced or played 

1) Kt+B+K vs lone K (pawnless ending). What was the outcome?

2) 2B+K vs K  (pawnless ending). What was the outcome?

3) how many years have you played chess? how many games of chess have you played ?(including regular, CC, real-time, blitz and lightning/speed)

I will start first:

1) Never

2) Never

3) About 15 years. I think I reached more than 1000++ chess games. I never faced pawnless minor piece endings. Most pawnless endings I faced/played are Q or R vs K.

i guess im second then...

1) never

2) yes, once. and it took me about 20 moves to checkmate him, after the last pieces were traded off(other then the 2 bishops)

3) 10 years and 500-750 games maybe (thats a guess, but probably close) 

 have you ever studied the 2B vs K checkmate?

1) never

2)a couple of times. the result was a victory.

3) a long time. on and off and always fun.

1) im guessing ur asking knight+bishop+king vs lone king... I havnt played this in a real game but on chessmaster 11th edition u can play against the computer with those pieces. You can always checkmate if you  have a knight and a bishop vs a king (just takes a bit of practice)

2) also not in a realy game and again have  played this in chessmaster and chess mentor and you can always checkmate

3) Ive been playing for bout 4 monthes and ive played 300ish games. Most have been long (10 mins plus 15 secounds per game) and latly ive started to play 5 min blitz games with good results. Ive played errm bout 30 turn based games on chess.com (rated 1470)

 me? now i have, but that game came early in my career and it took me a little to figure out what to do

1. Never

2. Never

3. Just a few years, but I've logged over 7,000 games online, play at a weekly club and played every day for hours at my coffee shop for about six months. 

To tell you honestly I never met anyone that faced 2Kt vs K + P yet. Lilienthal must be very lucky/cursed to face that kinda of ending 3 times !!

 These 2kts vs k+P or Kt+B vs K endgames require some study time and maintaing that knowledge and the probabilities of facing them are so small (less than 0.001%) why bother with them.

chessmaster makes it easier to study kt+b vs k... lol i still have to complete the challenge (tried it once for a couple mins and left it for another day)

Lousy> These 2kts vs k+P or Kt+B vs K endgames require some study time and maintaing that knowledge and the probabilities of facing them are so small (less than 0.001%) why bother with them.

+ It takes maybe 4.5 hours to learn and 1.5 hours / year to maintain B+N. It's not so difficult as some people make it out to be.

+ The benefits of learning how to coordinate B+N go beyond the simple mate, indeed, that's one of the biggest reasons to learn it.

+ The chance is 0.02% that a particular game will end with a B+N, but being confident you can handle B+N will affect more of your games because you won't be worried about trading down to that ending, just like a knowledge of pawn endings helps in many rook endings.
