Hi The Swine.
I think you are asking about here, White to play.
His Queen is where his Knight should be and I'm castled.
It's an advantage in time I must cash in this advantage for a solid structural
advantage. A time advantage will evaporate into nothing if I don't use it.
His Bishop is his best looking piece. My c1 Bishop is doing nothing so 11.Be3
it is developing with a threat. (Bxc5).
Black trading on e3 opens up the f-file and will boost the coming d4. I was I
suppose expecting 11...d6 or 11...Bb5 his 11....Ba7 was a baddie.
I traded on a7 12.Bxa7 Rxa7.
Because his Rook was now undefended and that meant Nb5 practically forced
him to play axb5 and I win the exchange with a tempo kick on the b7 Bishop.
(The tempo kick on the Bishop is more important than the exchange. The exchange
is a bonus, against undeveloped positions tempo kicks can lead to bigger things.)
A good move Nb5 but I played 13.d4 first so the tempo kick on the Bishop
gave him the e-pawn which opens the e-file for my f1 Rook (which happened)
also I was most likely thinking if after 13.Nb5 axb5 14. Rxa7 he can play 14...Qb6.
White is still winning but I have to move or defend the Rook (I'm losing time)
he can play d6, Qc6,Ne7/f6, 0-0....my time plus has gone all I have is the exchange.
(never over estimate the exchange when you have a time plus. Often when
you win it the time has gone. )
I wanted more. I wanted the exchange and the time.
Greed has it's place chess.
Not material greed that is one of the deadly sins.
Positional greed. You can never have enough positional advantages and
time is a positonal/tactical plus don't fritter it away.
So I threw in 13.d4 exd4 first because if after 14.Nb5 axb5 15.Rxa7 Qb6
I can play 16.Qxd4.
And White is winning that much more easily than the last diagram and
after 16...Qxd4 (16...c5 17 Rxb7!) 17.Nxd4
I still have the tempo kick on the Bishop and no matter where it goes I'm
I'm keeping my time and development plus. Always want more.
