It was good enough compensation. Shredder sees it as roughly equal.

The king was hellishly exposed given the B,Q and B lined up to pounce!

The RxN g2xN sequence is basically OK. Black can do better than the move
played with something like 12. ... d5 12. cxd5 Nd4 14. Qd1 Qxd5
and I think equality.
BTW any chance you could modify Getclub so that it shows captures with
the conventional "x" notation instead of "-" it makes life easier for
humans!
>24. Ne4-g5{26} Qh5-g5{60}
24. ... QxN was a bit optimistic and premature. BxN piles on the
pressure.
>31. Rg5-e5{30} Re8-e5{12}
This is among the worst captures. Either of Bxe5 or bxc5 would hold onto
white advantage. And about half of all moves are better than Rxe5.
>44. Qe3-e5{24} Qd5-e5{120}
QxB or Rb1 both look drawish (without looking too hard).
>49. Bb2-e5{36} Be7-g5{70}
Getclub might still be able to hold the game with the surprising
49. Rxa3 BxR 50. BxB KxP opposite coloured bishops. It would probably
lose the endgame against a human but it is close because of where the
pawns would have to queen. Any endgame experts shed some light?
>51. Ra1-c1{20} Bg5-c1{12}
Teasing the program with Bc1 ? Tut Tut. This is truly amazing. I cannot
see why a materialistic chess engine did not snatch your arm off here.
52. RxB and white is back in the game!

A bit risky against a stronger opponent but it was by no means bad.

See above. It was offered a chance to win as late as the 52nd move.
