42. 43-39! 19-24 (7-11 39-33) 43. 39-33 13-19 44. 47-41 07-11 45. 22-18 21-27 46. 18x07 11x02 47. 23-18 and white should win

42) 43-39 is also what I thought during the game. 22-18 13x24 34-30 19x28 30x19 14x23 25x5 is too expensive after 8-13 I think (21-27 36-31 27x36 43-39 might work for White because you immediately win back material, and 35 starts to run as well)
