Two players alternatively erase some 9 numbers from the sequence 1,2,...,101
until only two remain. The player that starts wins x−54 dollars from the
player that plays second, x being the absolute value of the difference between the remaining
two numbers.
Would you rather be the first or the second player?
Explain your decision by providing your strategy.

re: Typo? by Steve Herman)
Oh, you're saying nine numbers at a time. Sorry, my bad.
i.e. player 1 erases nine of the 101 numbers. Player 2 erases 9 of the remaining 92 numbers. Player 1 erases 9 of the remaining 83 numbers, etc. Correct?
Player 1 erases 54 numbers. Player 2 erases 45.
